To all 'whom t may concern:

Be it known that I, ULRICH KonNs'riiiN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hair-Drying Combs, of which the following is a specification.

My invent-ion relates to an improved construction of hair drying combs by which the comb is formed from sheet metal in a manner to use as thin metal as possible in the back of the comb without sacrificing strength in the teeth, since the latter are formed by folding the sheet of metal upon itself as will more fully appear below. My invention also consists in rigidly securing the handle of the comb t0 the hollow back thereof and providing the heating core or rod with a separate handle, so that both. parts of the device may be manipulated without burning the hands and in further providing a spring catch for holding the heating core in place in the hollow back. By my invention I further provide that the hair being dried may come directly in contact with a portion of the hollow back of the comb by cutting teeth the full depth of the projecting sheet of folded metal extending from the hollow back, as a result of which the heat of the core is communicated directly to the hair through the hollow back with a minimum loss by radiation.

Several drawings -illustrating my invention are as follows:

Figure 1 shows the comb in side view with the heating core partially inserted therein, and

Fig. 2 is a transverse sectional view through the comb shown in Fig. 1, taken along the line 2 2.

Similar numerals refer to similar parts throughout theJ several views.

As shown in the drawings the comb consists of a thin sheet of metal, preferably of aluminum, or other metal having good heat conducting properties, which is formed along one edge into a tube 10, the other edge being bent outwardly radially of the tube to form the teeth 11, and the outwardly extending portion being folded back at the points of the teeth upon itself so as to make the teeth 11 of double thickness, as

indicated more clearly in Fig. 2, the edge of the folded portion of the teeth preferably extending as indicated in Fig. 2 lto the inside of the bore of the tube 10. rIlie teeth Speccation of Letters Patent.

11 are formed by cutting slots through the outwardly extending double portion, which slots extend preferably to the outer surface of the tube 10 as a result of which the hair 1.2, being dried by the use of the comb, occupies'a position somewhat as shown in Fig. 2 directly against the outer surface of the tube 10. A handle 13 is rigidly secured to the tube 10 by riveting or otherwise, so that the comb may be conveniently operated and said handle is preferably of wood or other non-conductor of heat, so that the hand of the operator will not be burned in using the comb.

'A heating rod or core 14 is provided of slightly smaller diameter than the bore of the tube 10 which rod has rigidly secured to one end a handle 15 of wood or other nonconducting material, so that the heating rod may be handled without danger of burning the hand of the operator. The handle 15 has rigidly secured thereto a spring 16, the extending end of which is perforated at 17 to engage a pin or equivalent projection 18 from the outer surface of the open end of the tube 10 as a result of which the rod 14 is securely held in place in the tube 10 during the use of the comb.

rIhe comb is used by first removing the rod 14 from the tube 10 by lifting the end Of the spring 16 after which the rod 14 is heated and then inserted in the tube 10. The heat of the rod is communicated to the tube 10 and thereby to the teeth 11, and since the teeth are twice as thick as the tube 10 and good conducting path is afforded to the hair being dried, and furthermore, the hair coming directly in contact with a considerable portion of the outer surface of the tube 10, a large part of the heat is communicated directly through the wall of the tube 10 with a minimum amount of heat lost to said hair in contact with said tube.

I do not limit myself to the exact detail of construction shown and described above, as I may employ equivalents thereof known to the art at the time of the filing of this application.

I claim:

1. In a hair drying comb, the combination of a sheet of conducting metal formed into a tube and having teeth of double thickness extending therefrom, a non-conducting handle rigidly secured to said tube, a metal heating rod, and a non-conducting handle rigidly secured to said heating rod, said,

teeth being eut substantially to the outer surface of said tube and the folded portion of t-he sheet forming the teeth extending into the wall of the tube.

2. A huir drying comb comprising a sheet of metal forlned into a tube and having projecting vteeth formed from saidV sheet by folding the sheet of metal upon itself :it the outer ends of said teeth, whereby the vteeth are of double the thickness of said tube and the folded portion of the sheet forming the teeth extends to the inside of the tube.

3. A hair drying `comb comprising a. sheet of metal formed into u tube and having projeeting teeth formed from said sheet by folding the sheet of metall upon itself ut the outer ends of said teeth, whereby the teeth are of double the thickness of said tube, seid teeth extending` inwardly to the outer sur- ULRICH KORNSTEIN.
